摘要： Techniques for estimating data-to-pilot ratio are described. A terminal may receive pilot sent to multiple terminals and may receive data sent specifically to the terminal. The terminal may estimate channel gain and noise variance based on the received pilot. The terminal may then estimate a data-to-pilot ratio based on the received data y and the estimated channel gain h and noise variance σ2. In one design, the terminal may determine a metric  y  2 - σ 2  h  2 and may average the metric across multiple received data symbols to obtain the data-to-pilot ratio. The terminal may receive pilot and data via multiple antennas and may combine the received data across these antennas to obtain combined data. The terminal may estimate signal-to-noise-and-interference ratio (SINR) based on the received pilot from the multiple antennas and may then estimate the data-to-pilot ratio based on the combined data and the estimated SINR.

摘要： A user equipment (UE) generates a positioning state information (PSI) report that is transmitted to a network entity in a lower layer channel container, e.g., in the Physical channel or Medium Access Control channel, to reduce latency. The PSI report may be generated based on a plurality of PSI report elements determined from positioning measurements performed by the UE. Each PSI report element includes information related to positioning measurements performed by the UE. One or more of the PSI report elements may be compressed based on a compression configuration, in order to reduce overhead. If the size of the PSI report elements, after one or more PSI report elements are compressed, is larger than the lower layer channel container, one or more of the PSI reports may be omitted from the PSI report. A network entity may receive and process the PSI report based on the compression configuration.

摘要： Methods, systems, and devices for wireless communication are described that support a low peak-to-average power ratio (PAPR) precoded reference signal design for multiple-input, multiple-output (MIMO) transmissions. A user equipment (UE) may identify multiple sets of symbols associated with different reference signal waveforms, where each reference signal waveform may be associated with a low PAPR. In some cases, different single-carrier reference signal waveforms may be mapped to subsets of frequency resources through frequency division multiplexing (FDM) for a transmission on a single antenna. However, the addition of single-carrier waveforms through FDM for a transmission via an antenna may result in an uplink transmission having a high PAPR (e.g., as compared to single-carrier waveforms). The UE may reduce the PAPR of the uplink transmission by multiplexing the reference signal waveforms in the time domain (e.g., using time division multiplexing (TDM)).

摘要： This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for a user equipment (UE) entering a dormant state with respect to a secondary cell group (SCG) of a node network (SN) having a primary serving cell (PSCell). In one aspect, the UE may maintain a parameter set for at least the PSCell while the UE is in the dormant state with respect to the SCG. For example, the UE may receive a parameter change message from either the SN or a master network (MN) and transmit a parameter change acknowledgment to either the SN or the MN. The parameter change message may be transmitted as one or both of a downlink control information (DCI) or media access control (MAC) control element (CE). The UE may transmit physical layer measurements to the SN based on the parameter set.

摘要： Techniques for transmitting configurable pilots in a wireless communication system are described. The placement of pilots is determined based on an assignment of resources for transmission. Different placements of pilots are used for different assignments of resources. The assignment may be for one or more frames and/or one or more H-ARQ interlaces. The placement of pilot(s) in each frame or H-ARQ interlace may be determined based on the placement of pilot(s) in prior frame(s) or H-ARQ interlace(s). Pilots are sent at time and frequency locations determined by the placement of the pilots. Each pilot may be sent on one or more subcarriers in one or more symbol periods. The pilots may be TDM pilots and/or some other type of pilot. The pilots may be sent using IFDMA, LFDMA, EFDMA, OFDMA, or some other multiplexing scheme.

摘要： A method and transmitter for generating a transmission signal are disclosed in various embodiments. In one step, a first magnitude relationship of a received first plurality of symbols is determined to see if it qualifies for modification. At least one of the first plurality of symbols are modified when the first magnitude relationship qualifies to produce a second plurality of symbols.
